` RAZOR-BLADE SHARE'ENER.

T o all whom it may concern.'

Be it known that I, BENEDETTO YP. SIMONE, av citizen of the United States, residing at Providence, in lthe county of Providence and State of Ihode Island, have invented certain new and useful Improvements in Razor-Blade Sharpeners, of which the following is a specification.

My invention relates to a razor blade Sharpener of the rotary type and has for its essential objects, compactness, strength,`

v Figure 1 1s a top plan view of my novel device,

Figure 2, a side elevation of the same showing a portion of the side wall thereof broken away,

Figure 8, an end elevation of the same,

80 and Figure 4, a section of the plate holder and attaching plate taken on line 4-4 of Figure 1.

Lilie reference characters indicate like parts throughout the views.

In detail my device consists of an oblong box 6 having an open top, and comprises side walls 7, end walls 8, and a base 9. The walls have ornamental corner plates 10 fast to and covering the corners of the box. Journaled in the side walls is a transverse shaft 12 rotatable by a crank, pulley, or otherwise. In this instance a grooved pulley 13 is shown as the driving element. In

the side walls also are lubricating holes 14 extending from the admission plates 15, fast to the top faces of the walls, to the shaft. Fast to the shaft is a solid broad wooden roll 17 located between the walls and projecting slightly above the same, whose periphery is covered by a band 18 of leather or other stropping or abrading material.

An upright 2 0 is fixed to one end wall.v

Applicationiled .Tune 16, 1922. Serial No. 568,721.

In this case it is seated in a vrectangular recess 21 in the end wall, and recesses 22 1 n the side walls. An attaching plate 24 1s fiired to the upright by screws 25 and has integral with its lower end hooks or hinge sleeves 27 embracing a pintle 28. A pair of clamping plates 30 are provided with integral `resilient arms 31 at their rear ends connected by an end loop w32 embracing the pintle. The clamping plates are thus pivoted upon the described hinge structureb- Thesevplates are strengthened, their clamping action enhanced, and capacity for shoult dered blades afforded by reason of transverse swells 34 near their free ends. A clamping screw 36 passes through perforations 37 in intermediate portions of the plates. The screw head 38 is below the plate,

and upon the screw above the plates is threaded a clamping nut 40. ,n

The plates 30 are normally held downwardly into close Contact with the peripheral covering 18 of the roller by a helical f spring 42 fast at one end tothe screw 36 between the screw head and plates, and at the other end to ahook or pin 44 in the wall 8 below the upright.

In Figure 2 is shown a safety razor blade 46 carried between the plates 30 and bearing against the band 18 of the roll 17, whereby sharpening or stropping is effected by rotation of the latter.

' I claim:

In a razor blade Sharpener, a box, a driving shaft rotatably mounted in the boX transversely thereof, a roll fast to the shaft within the box and projecting slightly above vrthe box, a peripheral band of strop-ping materia-l upon the roll, an upright upon one end of the boX, an attaching plate fiXed'to the upright, hinge sleeves upon the attachplates, and a spring supported'by an intermediate portion of the plates and fast tol vthe box lbelow the pintle.

In testimony whereof I have" affixed my signature,
